CARL BYDELL. OFMANILA, PHILIPPINE ISLANDS.

LIFE-SAVING APPARATUS.

Application filed April 53, 1913. Serial No. 759,?16.

To all whom may concern:

Be it known that I, CARL RYDELL, a citizen of the United States, residing at Manila,

Philippine Islands, have invented new and useful Improvements in Life-Saving Apparatus, of which cation.

This invention relates to life saving appa ratus and has particularly to do with life boats.

()ne of the principal objects of the invention is the provision of means whereby a to occupy small deck space, thus enabling the ship to carry an adequate supply of life boats on a deck space which is wholly inadequate to carry the proper supply of boats where they are arranged singly.

Another object of the invention is to provide a sectional life boat which is adapted to be nested into other similar'boats and set up in a rapid and thoroughly durable manner..

A further een of the invention is the provision of .a'novel form of storm cover which may be readily set up and applied to the boat to protect the occupants thereof from the elements. 7

Still another object of the invention is the provision of a life boat having air tubes arranged along the side at a predetermined level so as to prevent the boat from capsizing and which is also provided with removable air tanks at the end so 'as to permit the boat to be nested with other similar but larger boats.

Further objects of the invention wlll appear as the following description is read in connection with the accompanying drawing. which forms a part of this application, and in which}?- Figure 1 is a side elevation of one of the boats'with'its improved form of sea anchor out with the improved type of cover mounted thereon. Fig. 2 is a perspective view showing the separate sections of one of the boats and indicating their method of connection. Fig. 3 is a side elevation of the nested boats. Fig. 4 is a vertical sectional view therethrough. Fig. 5 is a vertical section on the line 5-5 of Fig. 4. Fig. 6 is a detail longitudinal section taken through the boat. 'Fig. 7 is a detail bottom plan view, Fig. 8 is a detail perspective view of one of the boats: with parts broken away to show the method 'ofconnecting the air. tanks. Fig.

thefollowing is a specifis Patented May a, 1915.

- 9 is a perspective View of one of the thwarts looking from the bottom. Fig. 10 is a de tail perspective viewfshowing the manner of connecting the. storm cover to the boat and the method of supporting the same.

In thespecific embodiment of the invention as illustrated herein, the ,boats are ar ranged in what may be termed boat groups each consisting of three boats 1, 2 and 3, gradually decreasing in size and each pro vided with removable air tanks 4 so as to permit them to nest together in the position shown in the drawings. Each boat 2 and 3 comprises an intermediate section 5 having a false bottom 6 which forms an air compartment 7. The bottom 8 of the section is provided with the usual keel 9 and the false bottom has what may be termed akeelson supporting strips or battons 12 upon which are removablymountedthe seats or thwarts 13. These seats or thwarts "ha-V6 hinged to their underside, in the center thereof, suitable supporting standards 15% which are adapted to engage the clips so as to be held against accidental displacement. In each end of the section 5 a suitable bulk head 15 is secured in place and projecting beyond the bulk head on the top, sides and bottom of the section are flanges 16 adapted to receive simiiar iianges 17 upon the air tanks 4. The flanges 11' on the sides of the air tank are apertured as shown at 18 and flanges 16 on the sides of the section 5 are similarly apert'ured at 19 to receive connecting boltsQO by which the air tanks may be joined to the bulk head. The flange 16 which extends out from the top of the bulk l 1"ead is provided with hinge knuckles 21 adapted to interengage with similar hinge knuckles 22 formed on the tank 4 so that they may receive connecting bolts 23 extending inwardly from either side at the bottom of thetanh' and projecting outwardly from the flange 17 are separated cars 24: adapted to straddle the keel 9 and 26 having a loop 2? formed therein to receive the lowering tackle. These bars are corn nected to the, section by straps 28 and 29 both of which are bolted to the sides of the section as shown. The intermediate portion of each rod has an eye bolt 30 surrounding the same and which is adapted to be bolted to the inside of the bulk head 15. Secured on the outside of the boat by means of the clips or clamping bands 31 are air tubes 32 which extend the full length of the section 5 and are arranged approximately six or seven inches below the rail. These tanks act in the manner of sponsons and prevent the upsetting of the boat.

The endthwarts or seats are preferably formed as water-tight boxes which are adapted to carry provisions and water. One of the other thwarts may be provided with a box for carrying night signals and other paraphernalia. The boat 2 of each group is similar in every respect to the boat 1 except that its tanks are removable so that it may fit into the boat 1 as shown while the boat 3 is similar in every respect to the boat 2 except smaller so that it may nest into the boat 2. The air tanks of both boats 2 and 3 are arranged in the boat 3 when they are nested and other paraphernalia of the boats other than the thwarts therefor cannot be stored therein but are packed in the top boat convenient for ready removal when it is found necessary to launch the boats. Each of the boats 2 and 3 have their air tanks provided with an eye bolt 33 by which the same may be raised by the lowering tackle in connecting the air tanks with the intermediate section 5 which section of the boats 2 and 3 is supported by a pennant 34 depending from the outer end of the davit 35.

Each of the boats is providedwith storm covers 36 which have their ends secured as at 37 to the bulk heads 15. The side edges ofthe covers have secured thereto hingedly connected strips 38 aper'tured to receive securing bolts 39 by which the edges of the covers are secured to the rail of the boat. The central portions of the covers which are preferably constructed, of oil canvas are supported by removable bows 40 extending through the rail and. having their ends seated in clips 41. Each cover extends from the bulk head 15 to an intermediate portion of the boat and their free edges are reinforced by bows 42 adapted to be lashed or otherwise secured to the bows 40. The ends of the opposite covers on the boat do not meet but are joined together by a shoulder piece 43, also of oil canvas which may be furled to one of the bows 42 and have a removable connection with the' opposite bow. Suitable end pieces 44 are removably se cured to the bows 42 and extend downwardly where they are connected beneath a strip or plate 45 which conforms to the outline of the boat. The upper portion of these end pieces 44 is hinged and has a flap covered opening 46 which permits ventilation of the compartments closed by both end pieces. The intermediate compartment is provided with suitable thwarts 47 which are raised above the thwarts 13 and provide seats for the oarsmen. The boats are preferably steered with a steering oar which is practical in a rough sea and may be more conveniently stored.

Each boat carries a sea anchor which comprises a flexible steel cable 48 connected to a buoyant hoop 49 carrying a flexible cone shaped retarding device 50 provided with an aperture in its apex to prevent the canvas from bursting when under pressure. This type of anchor with a suitable sinkable hoop has been used before but the same is not practical on account of the fact that. it sinks too far to be of practical value. This type of anchor having a buoyant hoop floats light and keeps the anchor line tight so as to prevent sheering to either side.

With this type of life saving apparatus it will be noticed that no provision need be made for excessive deck space as in the case where it is necessary to supply a sufficient number of life boats to accommodate all the passengers and the crew, arranged singly upon the deck. By this arrangement the deck space may be reduced two-thirds.

What is claimed is z- I 1. In combination, a boat group consisting of a'plurality of boats, certain of which have removable air tanks to permit them to be nested in other boats, the intermediate portion of said boats having bulk heads, means connected to the intermediate portion for receiving lowering tackle, means for connecting said last-named means to the bulk head, and means for supporting the air tanks while the sections are assembled.

2. A life boat comprising intermediate and end sections, said endsections being in the form of air tanks, bulk heads at the end of the intermediate section, means for hingedly connecting the air tanks to the upper edge of the bulk head, said sections having heels, and means for attaching the keel of the end sections to the keel of the intermediate section.

3. A. life boat comprising an intermediate section, end sections removably connected thereto, a removable cover extending the full length of the intermediate section and having foldable end sections, and an intermeagre Q a removable cover extending the full length ment forming members connected to the cover andextendjng to the bottom of the intermediate section.

In testimony whereof I aflix my signature in presence of two witnesses.
